Abstract：The effect of manufactured sand morphology on mortar fluidity based on a multi-algorithm(MA)cross and BP neural network model was studied.The results indicate that the order of influence of morphology feature parameters on fluidity is sphericity>roundness>edge angle>specific surface area>elongation>aspect ratio>fractal dimension>flatness.The preferred parameters are sphericity,roundness and edge angle.Fluidity is positively correlated with sphericity and roundness,while negatively correlated with edge angle.The BP neural network model based on the preferred parameters can accurately predict the mortar fluidity.It is instructive to establish or improve the prediction model of the performance of manufactured sand mortar and realize the large-scale application of manufactured sand.
